Taking loperamide with other medicines and herbal supplements

There are some medicines that can affect how loperamide works.

Tell your doctor or pharmacist if you're taking:

• clozapine, a medicine used to treat mental health conditions
• ritonavir, a medicine for HIV infection
• quinidine, a medicine for abnormal heartbeats or malaria
• itraconazole, medicines for fungal infections
• gemfibrozil, a medicine for high cholesterol
• desmopressin, a medicine for bedwetting or peeing too much
• other medicines for diarrhoea, constipation, or any other stomach and bowel problems

Speak to your doctor if your diarrhoea is very severe and you take metformin for diabetes, or medicines for high blood pressure or heart failure. Your doctor may tell you to stop taking these medicines for a few days until your diarrhoea is better.

There's not enough information to say that complementary medicines and herbal remedies are safe to take with loperamide. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.

Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.
